Romans 3:6 - Coke's Commentary on the Holy Bible

God forbid!— This verse is the Apostle's answer to the Jews, which he crowds in while the Jew is going on with his observation. In reverence of the Divine Majesty, who is perfectly righteous, he qualifies the mere supposition for a moment of his being unrighteous (though this is proposed only for the sake of argument) three ways; first, by putting it into the form of a question, Is God un-righteous? Secondly, by adding immediately, that he spoke in the person of another, and as a man might say who was arguing that the casting off the Jews was a thing inconsistent with God's righteousness. Thirdly, by interrupting the Jew with a strong assertion of the most perfect righteousness of God, in the words of Abraham, Genesis 18:25. We have a similar instance of crowding in an answer while another person is speaking, Hor. lib. 2: sat. 3 ver. 187.
